How to convert JSON string in Array. Array within Array stuck me. How to handle with it?

Question

I have a JSON String. I want it to be filled in Array. Here is Array which i receive.

My JSON Response is:

{
    "model": "SyncData",
    "unique_id": "c12fb356f90d032b",
    "key": "sdjvnsdivbsnd",
    "sync_data": {
        "array_a": [{
            "a_fav": "true",
            "a_id": 1
        }, {
            "a_fav": "false",
            "a_id": 2
        }],
        "array_b": [{
            "b_fav": "false",
            "b_id": 8
        }],
        "c_array": [{
            "c_fav": "false",
            "c_id": 15996
        }],
        "patient_list_array": [{
            "unique_id": "sdvsdvsdvdsdv",
            "p_status": "false",
            "p_id": 1454943805215,
            "p_note": "2",
            "p_code": "8",
            "p_timestamp": 1454943805216,
            "p_name": "ABC XYZ",
            "p_status": 1,
            "p_room_no": "5"
        }],

        "array_d": [{
            "d_assigned_id": "30",
            "d_fav": "true"
        }]
    }
}

I want to store all this data in Array and from that in DataBase.

Use json_decode($string, true) also this is an object, which contains other properties that are arrays. I suggest you leave it as an object so dont use the second parameter i.e. ,true — RiggsFolly

if just in array format json_decode($string, true) , if remove second param u will get the result in object form. — devpro

To be clear, your talking about transforming JSON into native PHP data types. — Jon Surrell

If you want this json string in an array than you can use

json_decode($string,true);

Note that, second param of json_decode will return the array if you need result in object form than remove the second param "true".

Your Code:

$string = '{
    "model": "SyncData",
    "unique_id": "c12fb356f90d032b",
    "key": "sdjvnsdivbsnd",
    "sync_data": {
        "array_a": [{
            "a_fav": "true",
            "a_id": 1
        }, {
            "a_fav": "false",
            "a_id": 2
        }],
        "array_b": [{
            "b_fav": "false",
            "b_id": 8
        }],
        "c_array": [{
            "c_fav": "false",
            "c_id": 15996
        }],
        "patient_list_array": [{
            "unique_id": "sdvsdvsdvdsdv",
            "p_status": "false",
            "p_id": 1454943805215,
            "p_note": "2",
            "p_code": "8",
            "p_timestamp": 1454943805216,
            "p_name": "ABC XYZ",
            "p_status": 1,
            "p_room_no": "5"
        }],

        "array_d": [{
            "d_assigned_id": "30",
            "d_fav": "true"
        }]
    }
}';

$array = json_decode($string,true);
echo "<pre>";
print_r($array);

Result:

                            [p_room_no] => 5
                        )

                )

            [array_d] => Array
                (

                            [d_fav] => true
                        )

                )

        )

)

Thanks. Got the solution. With some improvement i can use this.

Simple code to use to visualise your JSON String

<?php
$string = '{
    "model": "SyncData",
    "unique_id": "c12fb356f90d032b",
    "key": "sdjvnsdivbsnd",
    "sync_data": {
        "array_a": [{
            "a_fav": "true",
            "a_id": 1
        }, {
            "a_fav": "false",
            "a_id": 2
        }],
        "array_b": [{
            "b_fav": "false",
            "b_id": 8
        }],
        "c_array": [{
            "c_fav": "false",
            "c_id": 15996
        }],
        "patient_list_array": [{
            "unique_id": "sdvsdvsdvdsdv",
            "p_status": "false",
            "p_id": 1454943805215,
            "p_note": "2",
            "p_code": "8",
            "p_timestamp": 1454943805216,
            "p_name": "ABC XYZ",
            "p_status": 1,
            "p_room_no": "5"
        }],

        "array_d": [{
            "d_assigned_id": "30",
            "d_fav": "true"
        }]
    }
}';
$obj = json_decode($string);
print_r($obj);

Which will output :
